Meanwhile, The Michigan Department of Human Services director says the department had petitioned the court to remove an 8-year-old Detroit girl, who was found stabbed to death Sunday, and her siblings from her mother's care about a month before her death.

DHS Director Maura Corrigan says the department had unsuccessfully asked the court to remove Tameria from her mother's care and a court-ordered in-home visit had occurred just two days before the girl's death.

"DHS acted on the concerns reported by Tameria’s family, friends and neighbors, including petitioning the court for removal of the children from the home dating back to 2010," said Corrigan in a statement released Wednesday. "Most recently, DHS petitioned the court on Nov. 28, unsuccessfully, to remove Tameria and her siblings from their mother’s care. DHS continued to provide court-ordered counseling services to the family as well as conducting in-home visits, the last of which occurred only two days before Tameria’s death. We share the grief felt by her loved ones and her community."

"Following the tragic death of Tameria Greene, I ordered an expedited, comprehensive review of this case from the Office of Family Advocate, a centralized unit within the Department for reviewing complaints about the handling of child welfare cases," said Corrigan.

Former Oakland County prosecutor David Gorcyca says a full investigation needs to be launched in order to determine who dropped the ball.

"I would go back and look at each petition that was filed, whether it was authorized and why it wasn't authorized," he said.
